  • We generalize the bumpy black hole framework to allow for alternative theory deformations. We construct two model-independent parametric deviations from the Kerr metric: one built from a generalization of the quasi-Kerr and bumpy metrics and one built directly from perturbations of the Kerr spacetime in Lewis-Papapetrou form. We find the conditions that these 'bumps' must satisfy for there to exist an approximate second-order Killing tensor so that the perturbed spacetime still possesses three… CONTINUE READING
